During combustion, the outer surfaces of the stove will become hot, and due care must
therefore be shown.
Fuelling with coal, patent fuel or carbonised coal
The stove is not designed for fuelling with coal and carbonised coal. However, patent fuel can be used
to fuel the fire and should be placed on the embers produced by the burned wood.
Be aware that using fuels other than wood, will cause soot to form on the glass pane.

Rapid or fierce heat
Rapid or fierce heat is obtained by burning many small pieces of wood.
Maximum amounts of fuel:
The maximum allowed amount of fuel per hour is:
Wood: 2.0 kg
If these limits are exceeded, the stove will no longer be covered by the factory guarantee, and it may
also become damaged due to excessive heat. The stove has been approved for intermittent use.
Typical re-firing interval
Typical re-firing interval at nominal performance
Wood: 65 min
Long burning times
Basically, the HWAM Autopilot IHS
TM
will burn as slowly and as economically as possible. The slowest
combustion is achieved by adjusting the thermostat on the remote control to level one.
How to achieve the best combustion
The HWAM Autopilot IHS
TM
is purposely designed to generate the cleanest and the most economical
combustion. A good combustion is achieved when the fire gets the right amount of oxygen supply at
the right time and place in the combustion chamber. The HWAM Autopilot IHS
TM
allows for varia-
tions in external circumstances. Nevertheless, it is important to use clean and dry wood (humidity
approx. 16-20%).
Cleaning the glass
We recommend wiping the glass after a fire. This is best done using a paper towel.
Types of fuel
The stove may be damaged by very high temperatures and the glass may turn white, for example. This
can be avoided by never allowing the stove to burn with the ashpan open and taking great care with
types of fuel that develop excessive heat, such as briquettes. If the flue gas temperature exceeds 550
o
Celsius, the HWAM Autopilot IHS
TM
will revert to safety adjustments and automatically turn down
the air valves to avoid overheating. When the temperature is reduced to 450
o
Celsius, the normal
functions apply again.
We recommend using birch or beechwood, which has been split and stored for at least one year out-
doors under cover. Wood stored indoors tends to become too dry and burn too quickly.
